Lockdown
The OPW Loading Arm Lockdown is designed to secure the loading arm in the down position during loading. Loading safety is improved by preventing the arm from lifting due to filling forces during loading. To engage the loading arm lockdown, locate the loading arm in the desired position and hand-tighten the lockdown handle to secure the arm.
Features/Benefits
- Designed to be used on 2", 3", 4" and 6" loading arms
- Simple twist-to-tighten locking mechanism—No preset lock positions
- Wide range of loading arm operation angles from +20° to -20°
- For use on loading arms with a 790 Torsion Spring
- Existing loading arms can be retrofitted with the new lockdown*
*Please see technical information for Retrofit options and limitations.
